Although familial hemophagocytic lymphohistiocytosis (FHL) generally manifest with a combination of unremitting fever, hepatosplenomegaly, and pancytopenia; unusual presentations should also be taken into account. Herein, we present 3 FHL cases with 2 novel mutations with different initial presentations. The first patient bearing a homozygous truncation mutation in UNC13D (c.2650C>T.p.Gln884Ter) presented with central nervous system involvement and skin rash. The patient responded to the HLH-2004 protocol, and allogenic hematopoietic stem cell transplantation was performed from her healthy sister. The second and third patients with homozygous splice site mutation (c.430-1G>A) in STXBP2 were siblings who presented at birth with fevers, elevated aspartate aminotransferase, alanine aminotransferase, and hyperferritinemia but did not fulfill FHL criteria. The last 2 infants died despite intervention. Hematologists should be vigilant about the different presentation of FHL in children.
